415848 divided by 40 
Let's see how many times 40 fits into 415848.

Let's proceed to step 1:
40 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 40

Step 2:
When dividing 41 by 40, we get 1 with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 40 from 41, we get 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 40

Moving on to step 3:
The number 40 fits into 15 0 times, leaving a remainder of 15.
The next digit of our result is 0. 
Result so far: 10.0
Subtracting 0 from 15 leaves us with 15.
Fetch the next digit (8) from the dividend, attach it to 15 and continue: 158 / 40

On to step 4:
If we divide 158 by 40, we get 3 and a remainder of 38.
Write down 3 as next digit of the result. 
Result so far: 103.0
If we subtract 120 from 158, we get 38.
Bring next digit (4) of the dividend behind the 38 and repeat the process: 384 / 40

On to step 5:
40 can be fit into 384 9 times, resulting in a remainder of 24.
Use 9 as the next digit of our solution. 
Result so far: 1039.0
If we take 360 away from 384, we end up with 24.
Grab the next digit (8) from the dividend, add it to 24, then carry on: 248 / 40

On to step 6:
The number 40 fits into 248 6 times, leaving a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 10396.0
If we take 240 away from 248, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 7:
40 goes into 80 2 times with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 10396.2
If we subtract 80 from 80, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
40 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 10396.2
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
0 divided by 40 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10396.2
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 10396.2 with a remaining 0.0.
